What should you know about loss of libido in men?

Desire naturally changes over time, but a noticeable change that lasts or causes distress deserves attention. Low mood, anxiety, burnout, poor sleep and relationship strain can reduce interest in sex. Depression may include reduced pleasure more broadly, while burnout can leave a person mentally and physically depleted.

Health conditions can also affect desire. Thyroid hormone changes and type 2 diabetes may influence energy, mood, nerves or blood flow. Some medicines, alcohol or other substances may contribute. Erectile difficulties can lead to worry and avoidance, even when desire itself has not disappeared. Reduced libido is a symptom, not a diagnosis; it does not by itself identify one particular condition.

Arrange a primary-care appointment if the change is persistent, sudden, distressing or affecting a relationship. Note when it began, whether desire varies by situation, and any changes in sleep, mood, erections, energy, weight or urination. Bring a complete list of prescribed medicines, supplements, alcohol and recreational substances.

A clinician may ask about mental health, relationships and general health, examine you when appropriate, and decide whether blood tests or another assessment is useful. Do not stop a prescribed medicine or start testosterone or sexual-enhancement products without medical guidance. Regular sleep, movement, balanced meals, moderating alcohol and making space for private communication with a partner may support recovery while the cause is explored.

Seek prompt medical advice when reduced desire comes with marked depression, loss of interest in other activities, thoughts of self-harm, severe tiredness, unexplained weight change, persistent thirst or frequent urination. Sudden sexual changes alongside chest pain, breathlessness, weakness, confusion or severe headache need urgent assessment. A clinician can also help sooner when medicines, substance use or relationship distress may be involved.

Ask whether a medicine, thyroid problem, diabetes, mood change or sleep issue could be contributing; whether any tests are appropriate; and which treatment options fit your health history. You can also ask how to discuss the change with a partner and whether counselling or sexual-health support may help.
